Summary of findings

  • Overview

    We carried out extensive end-user performance testing and have provided results and guidance based on the PAAC testing carried out with the NVIDIA nVector Knowledge Worker and Autodesk Maya-NVIDIA Omniverse collaborative workloads. The 3rd Generation Intel Xeon scalable processors and NVIDIA Ampere GPUs in our Virtual Workstation configuration provide performance, density, and agility for your VDI workloads.

    The configurations for VxRail are optimized for VDI, which includes memory and CPU configurations that provide optimal performance. You can change these configurations to meet your environment requirements, but changing the memory and CPU configurations from those that have been validated in this document will affect the user density per host. Work with your account team to size the solution and reserve resources for management tools when designing your VDI environment.

    With the changing dynamics of modern graphics-accelerated applications and the diverse set of user situations such as working from campus or working from home, IT teams face a challenge to provide a consistent user experience. This design guide presents performance validation of the expected end-user collaborative experience for the given validated design.

    Configuration considerations and best practices are discussed with specific focus on the overall experience for professional graphics-accelerated applications and 3D interactive collaboration.

    All Dell Technologies Validated Designs for VDI are configured to produce similar results. You can be sure that the vSAN-based appliances you choose have been designed and optimized for your organization's needs.

    User density recommendations

    The recommended user densities in the following table were achieved during performance testing on VxRail. We followed the VMware best practices of FTT = 1 and maintained a reserved capacity of at least 30 percent.

    Dell Technologies recommends that you test your own workloads and datasets. The recommendations provided in this guide are generalized guidance rather than a one-size-fits-all configuration. The degree to which higher scalability is achieved depends on the typical day-to-day activities of your 3D graphics users, and the concurrent nature or otherwise of their work.

    Several configuration attributes directly affect density scalability, such as virtual workstation parameters, GPU scheduling policy, and vGPU profile selection. It is recommended that you test and validate the appropriate configuration options to meet the needs of your users. The density numbers provided offer general guidance and are indicative in nature. Individual user circumstances require appropriate validation.
